These For Life brand teapots are very durable and highly functional. With hundreds, maybe thousands, of pots of tea made in each of ours, they pass the durability test. The extra fine stainless steel infuser comes with it and the handle on it helps you remove it without burning your fingers after your tea is steeped. They also stack nicely! The box shows them as 18 oz but we suggest putting about 16 oz of water in them. Dimensions: L 6.75" x W 4.5" x H 5.3"
